Scope: This specification covers the following four types of reinforcing material constructed from glass fibre and polyester fibre and suitable for imbedding in a bitumen or coal tar enamel protective coating on pipes: Amdt2 Type 1: A random glass fibre mat of relatively low tensile strength intended primarily for use as an inner wrap. Type 2: A woven glass fibre scrim, coated with bitumen or coal tar enamel, of high tensile strength in both longitudinal and transverse directions, with relatively low binder-holding capacity, and intended primarily for use in the outer layers of the bitumen or coal tar enamel coating. Type 3: A woven or bonded glass fibre scrim combined with random glass fibre mat to achieve a tensile strength in both directions similar to that of type 2 but with porosity and binder-holding capacity similar to type 1, and intended for use in the inner or the outer layers of the bitumen or coal tar enamel coating. Type 4: A polyester fibre stitchbonded substrate of relatively high tensile strength in both longitudinal and transverse directions, with high porosity and binder-holding capacity, and intended for use in the inner or the outer layers of bitumen or coal tar enamel coating. Amdt 2 NOTE a) The titles of standards referred to by number in the specification are given in annex A. NOTE b) Requirements that must be specified by the purchaser are listed in annex B.
